Like I said: It attacks their world view.

I'm playing the persona of a person that has been around the block a little too well perhaps to make a point. The fact is that there is always somebody more experienced, smarter, better than you are, no matter who you happen to be. Even if you are at the top of your game, changing the subject matter can easily knock you down a few pegs.

I appreciate that what I'm saying may be lost on the youthful part of this audience and may be taken as me saying that I am better than you all because I have a few years on you. Be clear: this isn't what I am saying. I'm no less of an audience to my own comments as anyone else reading them.
